I've been having pain in my armpits and scrotum for a long time now and nothing seems to help.

A couple years ago I wore some uncomfortably tight underwear several times in a row. I stopped because they were uncomfortable, but now I have aching pain on the sides of my scrotum. The pain is worse on the left, and it's not there all the time, but it is a lot. If I wear anything remotely tight, it gets worse.

About half a year ago, I was wearing a winter coat a lot that was too tight in the armpits, and once again I stopped wearing it because it was uncomfortable, but again, I now have aching (occasionally sore) pain in my armpits. It's worse on the left, comes and goes, and gets worse if I wear an even remotely tight T-shirt.

Any idea what this is or how to make it better? It's driving me crazy.

No idea what it is exactly, but I do know that when I have a flare of inflammation, I cannot sleep in my regular t-shirt style sleep garment.
